Abstract: Disclosed is a method of detecting filarial larvae in blood. The method comprises preparing a measurement sample from a blood sample collected from an animal; flowing the prepared measurement sample through a flow cell; irradiating light on the measurement sample flowing through the flow cell; detecting light given off from the irradiated measurement sample; and detecting filarial larvae contained in the measurement sample based on characteristic parameter of the detected light.

Abstract: A formulation and process for capturing CO2 use an absorption mixture containing water, biocatalysts and a carbonate compound. The process includes contacting a CO2-containing gas with the absorption mixture to enable dissolution and transformation of CO2 into bicarbonate and hydrogen ions, thereby producing a CO2-depleted gas and an ion-rich solution, followed by subjecting the ion-rich solution to desorption. The biocatalyst improves absorption of the mixture comprising carbonate compounds and the carbonate compound promotes release of the bicarbonate ions from the ion-rich solution during desorption, producing a CO2 gas stream and an ion-depleted solution.

Abstract: Methods and systems of maintaining, evaluating, and providing therapy to a lung ex vivo. The methods and systems involve positioning the lung in an ex vivo perfusion circuit; circulating a perfusion fluid through the lung, the fluid entering the lung through a pulmonary artery interface and leaving the lung through a left atrial interface; and ventilating the lung by flowing a ventilation gas through a tracheal interface. Maintaining the lung for extended periods involves causing the lung to rebreath a captive volume of air, and reaching an equilibrium state between the perfusion fluid and the ventilation gas. Evaluating the gas exchange capability of the lung involves deoxygenating the perfusion fluid and measuring a time taken to reoxygenate the perfusion fluid by ventilating the lung with an oxygenation gas.

Abstract: A method for detecting the presence or absence of an antibiotic resistant pathogenic staphylococci in a test sample is provided. The method includes the steps of: a) providing a test medium having at least one hydrolysable substrate, which substrate is operable to promote the growth of the antibiotic resistant pathogenic staphylococci and to produce a detectable signal when the hydrolyzable substrate is metabolized by the antibiotic resistant pathogenic staphylococci; b) forming a mixture of the test sample and hydrated test medium; c) incubating the mixture at temperatures in the range of about 20° C. to about 35° C.; and d) detecting the presence or absence of the antibiotic resistant pathogenic staphylococci in the test sample by the presence or absence of the detectable signal in the mixture.
Abstract: Cells present in adipose tissue are used to stroke and stroke related diseases and disorders in a patient. Methods of treating patients include processing adipose tissue to deliver a concentrated amount of regenerative cells obtained from the adipose tissue to a patient. The methods may be practiced in a closed system so that the regenerative cells are not exposed to an external environment prior to being administered to a patient. Accordingly, in a preferred method, cells present in adipose tissue are placed directly into a recipient along with such additives necessary to promote, engender or support a therapeutic benefit.

Abstract: Provided herein are methods, compounds, mixtures and formulations of antigen retrieval agent useful in retrieving antigens and improving the detection of amino acids, peptides and proteins or epitopes thereon in a tissue fixed with aldehyde-based cross-linking agents. Contacting the fixed tissue with a solution of the aldehyde scavenging agent causes reactivity with the aldehyde moieties to retrieve antigens and improve detection of the amino acids, peptides and proteins or epitopes. Also provided are kits comprising the antigen retrieval agent and, optionally, components for staining or detecting the proteins or the antigens or epitopes and instructions for using the kit. Further provided is a method for identifying an antigen retrieval agent. A fixed protein is contacted with an agent to be tested and heated in solution therewith. Detection of protein peaks via mass spectrometry indicates the tested agent is an antigen retrieval agent.

Trehalose or its derivative or a salt thereof is added to physiological aqueous solutions to prepare cell-washing solutions containing trehalose or its derivative or a salt thereof as an active ingredient. The cell-washing solutions can be used to wash adherent cells before detaching the adherent cells from a culture vessel by proteolytic enzyme treatment to suppress cell death due to the proteolytic enzyme treatment. The concentration of trehalose applied to the cell-washing solution may be a concentration capable of suppressing the cell death due to the proteolytic enzyme treatment, such as 0.1 to 20 (w/v) %.

Abstract: A method for differentiating forms of lymphoma involves analyzing a tumor tissue sample from a subject for expression of CD28, ABCA5, CCDC3, and SMOC2. The CD28:ABCA5 expression ratio differentiates T-cell tumors from B-cell tumors. The CCDC3:SMOC2 expression ratio differentiates different T-cell tumors. The method can further include administering to the subject from whom the sample was obtained an appropriate treatment for the form lymphoma identified by performing the method.
